摘要：PURPOSE:To enable the continuation of a tracking maintaining the accuracy, by

receiving a forecast signals outputted from a tracking filter, an output of an incident

angle calculator and an output of a device for determining the propriety of capture as

input to arrange a subsequent observation judging device which outputs the error

dispersion in the subsequent observation from a signal to a filter ring indicator, the

subsequent observation time and the forecast angle. CONSTITUTION:A subsequent

observation indicator 11 newly provided is made up of an antenna direction calculator 12,

an incident angle calculator 13, an existence expected area calculator 14, a device 15 for

determining the propriety of capture and a subsequent observation judging device 16.

Then, the calculator 12 calculates the direction of an antenna in the future by a time lT

and an incident angle at which one will see a target forecast in the future by the time lT,

for which the output of a forecaster 7 adapted to forecast a likely state at the future

time is obtained through a converter 9a. In addition, the size of the existence expected

area is calculated 14, but as it is expanded gradually unless a new observation is done,

thresholds are provided in three directions to determine 15 the propriety of capture.

Then, the judging device 16 judges the time of the subsequent observation based on

information to be inputted from equipments.
